Congrats! Now we can +1 the number of people who have solved this but aren't sure which step was the solution.
It does take a little while before the graphs will show data. RRD needs at least two primary data points before it can produce a graph. So, you have to wait at least STEP*2 before you still see anything on a graph. Assuming your STEP value is sane, there was probably some other reason you didnt see data for 14 hours.
